SPECIFICATION forming part of Letters Patent No. 559,465, dated May 5, 1896.

Application filed November 23, 1895. Serial No. 569,912. (No model.)

Z'c all whom it may concern:

Be it known that I, WILLIAM E. SHARPLEs, a citizen of the United States, residing at Fall River, in the county ofBristol and State of Massacl1usetts,have invented certain new and useful Improvements in Separator Mechanism for Ring-Spinning Frames; and I dodeclare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica tion.

This invention relates to the separators used on ring-spinning frames; and its obj ect is to improve the construction of the separator and also the mechanism for holding, adjusting, raising, and lowering t-he same.

In the accompanying drawings, Figure l is a side elevation of. a spindle of a ring-spin ning frame, showing two separators and the mechanism for raising and lowering them. Fig. 2 is a rear elevation of a portion of the same machine. Fig. 3 is a top plan view of a portion of the ringrail and separators. Fig. 4l is a detail view of the blank for one of the separators.

The roller-beam A, jointed thread-board B, guide-wire C, spindle-rail D, spindles E, bobbins F, mounted thereon, ring-rail G, carrying the ring'g and traveler g', the lifting-rods H I, attached, respectively, to the ring-rail and the support K for the separator-bar K', and the rock-shaft L, from which said rods receive their motion, are all old and may be of any desired construction. The separatorbar K is fastened to one leaf 7e' of a hinge, the other leaf, le, being attached to the support K. The bar can therefore be turned up into the position shown in dotted lines in Fig. 1. Each separator M is composed of a sheet of metal tangent to the bobbin and of a height preferably about twoiifths that of the bobbin. Its top and bottom are rounded, and its front edge is bent at a sharp angle to the blade of the separator, forming a flange m approaching the bobbin. The blade of the separator is provided with a number of vertical parallel inside ribs or bars m'. `These may be of any suitable shape, such as corrugations or projections, or simple bars left between slots cut in the separator. I prefer to form them, as shown in Figs. 1,2, 3, and el, by cutting slits m2 with a short .angular slit 'm3 at each end, thereby forming narrow leaves, which are bent inward toward the bobb'in in the direction of the movement of the revolving thread, as clearly shown in Fig. 3. In tegral with the blade of the separator is a foot m4, which is preferably formed with flanges to iit down over the sides of the separator-bar K'. The separator is secured adjustably to the separator-bar by a set-screw passing through a slot m5 in the foot m, whereby the separator can be adjusted along the bar toward or away from the bobbin.

The rock-shaft L carries a rock-arm L', in

the end of which is a slot Zfor the adjustment a wrist-pin n' engaging the upper end of the pitman O, which is made in two parts held together by the bolt o, so as to be adjustable in length. The lower portion of this pitman has a cup P, in which is stepped the lower end of a vertical rod I', which carries at its upper end a cup P', in which is stepped the lifting-rod I. The cavity in each cup is conical, so that the rods are permitted to rock on their steps. Each cup has a slot p on each side to receive the projecting ends of pins fi, which are driven tightly into the rods. The slots permit the rods to rock, but prevent them from being accidentally unseated. The rod I reciprocates in a bearing in the arm d, attached to the spindle-rail D.

f The upper ends of the separator-bar-lifting rods are connected by pivoted links R with blocks S, attached to the ends of the hangers T, attached to the roller-beam A by screws T passing through horizontal slots t, in order to provide for adjustment of the hangers and bars. The blocks S are vertically adjustable on the hangers by means of slots t' and bolts s.

Having thus deseribed'the several features' of construction, it remains to point out their functions and advantages.

' The peculiar construction of the separator IOO enables it to be set close to the inside diameter of the ring g, so that the thread in passing down from the guide-wire to the ringtraveler is kept in nearly a vertical line and is prevented from ballooning far from the bobbin. There is in consequence not so much drag on the thread, and a stronger and evener thread is produced. The object of the projections on the inner face of the separatorblade is to prevent the threads from whipping together by holding them for nearly onehalf of the revolution around the bobbin. Furthermore, they operate to knock off any loose bunches of lint or foreign matter adhering to the thread, and a cleaner and smoother thread is made. The angular form of the separator enables it to control the thread for a longer portion of the revolution, and yet the separator does not project so far in front of the spindle as to interfere with the ready removal of the bobbin. It is evident that the separator may have more than one angle and that it may even be curved to the segment of a circle, if desired, as indicated in dotted lines in Fig. 3.

The object of the pitman and the cupped steps P P for the separator-bar-lifting rods is to enable the rods to conform more easily to the changing positions of the rock-arms. The pins 'i connect these parts together, so that the downward movement of the rods is in the main positive, the entire weight of the rods and separators assisting in the downward movement, so that there is but little danger, if any, of the rods sticking.

The adjustability of the clamp N on the rock-arm is for the purpose of changing the traverse of the separatorbar. Being attached between the shaft and the ring-raillifting rod, the movement of the separatorbar-lifting rod is slower and of less extent than that of the ring-rail rod. In coming down the ring-rail gains on the separators, so that when it has reached its lowest position the separators stand some three inches above it, but not far enough to permit the threads to whip together. When the ringrail is rising, the separator reaches its highest position in advance of the ring-rail, so that at all times the separator is never in contact with said rail.

The object of the links R is to guide and stiften the separator-rods when the ring-rail is up to its highest position and prevent any movement endwise. It will be seen that the links swing in a plane parallel to the separator-bar, so that the separators move in arcs of circles in the direction of the length of the frame and toward and from the spindles.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A separator-blade adapted to stand at one side of the bobbin, and having on its inner face a series of vertical projections, substantially as described.

2. A separator-blade adapted to stand at one side of the bobbin, and having on its inner face a series of inwardly-projecting vertical leaves inclined in the direction of the movement of the thread, substantially as described.

3. A separator-blade consisting of a sheet of metal adapted to stand at one side of the bobbin, and having a series of vertical parallel leaves struck up from the body of the blade and inclined inwardly, substantially as described.

4. A separator-blade having a series of vertical parallel slits with short angular slits at each end, the metal bounded by said slits being bent inwardly to form a series of projecting leaves, substantially as described.

5. A separator-blade having the vertical slits m2, the angular slits m3 at the ends of the slits m2, and the foot m4 containing the slot m5, substantially as described.

6. A separator-blade having on its inner face a series of vertical projections m', its outer edge being bent to form a iiange m adapted to project in over the ring-rail, substantially as described.
